    private List <Order> orders ;
    private OrderIF orderif ; // this is 3rd party interface

       //some code 

       // this returns a list of objects (orders)
       orders = orderif.ordersFor(type);

       // some code 
       return orders.get(0)

public class ServiceImplTest {
     private List <Order> ll ;
     private service reqService ; 

     @InjectMocks
     private orderIF order;

     @Before
     public void setUp() throws Exception { …
